BACKGROUND AND SUMMARY OF THE INVENTION

Presently there is no system that allows persons working underwater to have mobile device communication, or to transfer data from a phone located underwater to radio or antenna on the surface of the water. In particular, the use of mobile devices underwater is particularly stunted due to the lack of ethernet connectivity underwater and the lack of data port plug-ins. For example, divers presently do not have the ability to connect to the surface of the water nor do they have full capability of a mobile device underwater. Methods used by divers and others working underwater include waterproofing cables by using heat shrink which is not an effective means to prevent water intrusion long term. Additionally heat shrink makes the cables unable to bend and flex, which is necessary in a dynamic environment such as the ocean. Cables used to try to enable devices to work underwater are used to dive once, but then the cable must be dried sometimes for days before being used again.

The present invention solves this problem by enabling divers and other underwater recreation or professions to use exemplary mobile devices while they are underwater. The present invention relates to underwater functionality of an exemplary mobile device via an exemplary buoy assembly connected via commercially available cables to waterproof data port plug-ins. The objective of the present invention is to establish connectivity to the exemplary underwater mobile device via a system of cable connections, where the cable connection antennae are kept above water no less than 95% of the time via the exemplary buoy system. The antennae could include GPS and other communication cables, but could further include any other antennae suitable to the purpose of the divers. The system of the present invention could also be used by anyone with the need for an underwater connection to surface signals via mobile device such as smart phones, tablets, ethernet-connected GPS devices, and other mobile devices that can be enabled by an ethernet connection. The design of the present invention preferably accommodates either smart phones or tablets.

The underwater mobile device is contained in a waterproof case that, in contrast to traditional touchscreen interfaces that do not work underwater, allows the full functionality of the touch screen mobile device to be utilized at any depth of immersion in water. The waterproof case additionally has an exemplary stylus pen that enables the full functionality of the exemplary mobile device at any depth of immersion in water. The underwater mobile device transfers data via an ethernet connection cable to an exemplary radio contained in the buoy, and antenna above the surface of the water.

The exemplary buoy assembly allows ethernet connectivity (for example, enabling GPS and communications) for use of navigation and communication technologies on the exemplary mobile device. The system of the present invention is further commercially applicable for any application requiring an underwater connection to surface signals, e.g., as required in tracking, underwater demolition, and commercial diving. For purposes of the present invention, the design of the exemplary buoy additionally makes little to no noise or splash, is hard to see, provides insignificant drag to the diver, and is retrofitted to provide continual connectivity with the communications systems plugged into the exemplary mobile device.

The exemplary waterproof case contains an underwater touchscreen interface case that has a source for an ethernet cable connection, a screen that can be touched through, a cable connector to connect to a surface antenna, and touch screen capabilities to a 10-inch touch depth, with a stylus pen as described above for full touch screen capabilities at greater depth.

According to a further illustrative embodiment of the present disclosure, the exemplary underwater touchscreen interface case is filled with air. The exemplary underwater touchscreen interface case of the present invention seals and protects any mobile device and permits native operation such as touch button pushing and the full capability of the device enclosed within it.

According to yet another illustrative embodiment of the present disclosure, the exemplary underwater touchscreen interface case need not be opened unless the phone itself malfunctions or breaks.

Additional features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrative embodiment exemplifying the best mode of carrying out the invention as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS

The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

Referring initially to FIG. 1, the entire system of the present invention, as would be used in an exemplary field of operation immersed in body of water 47 (not shown) with exemplary mobile device 49 in waterproof case 51 with connection to one end of cable 53. The other end of cable 53 can be connected to buoy 55. Cable 53 can be a water-resistant, flexible, and bondable cable. Waterproof case 51 seals and protects any exemplary mobile device and permits native operation, e.g., touch screen capabilities and button pressing.

Referring to FIG. 2a , a diagram of cable components showing water-resistant micro USB converter 205 coupling exemplary mobile device 49 in waterproof case 51 to 6-pin cable 209. Micro USB converter provides electrical connection and power and noise regulation. Leftmost on 6-pin cable 209 can be a high depth high-pressure electrical connector between waterproof case 51 and 6-pin cable 209, micro USB connector 153 (not shown). Micro USB connector 153 (not shown) connects into the connection port of an exemplary mobile device 49 internal to waterproof case 51. Exemplary splices 201 couple pieces of cable 53 together and extend the length of cable 53 to a desired length that can be approximately commensurate with the depth at which exemplary mobile device 49 is to be operated. After splices 201 are added such that the length of cable 53 is extended to the desired length, power converter 203 is coupled near the end of cable 53 and converts the voltage of cable 53. The end of cable 53 is then coupled to external connector 57 which connects cable 53 to radio 59 (not shown) via 19-pin ethernet cable 207 and is water-resistant and can be an in-line connector, and flange-mounted. Small silver cable 143 provides string relief that takes the force structure off of the electrical connections and away from the phone on a safer part of the body of buoy 55 (not shown).

Referring to FIG. 2b , a schematic of cable components showing 6-pin cable 209 connected to USB converter 205, with cable 53 running between USB converter, e.g., at an exemplary length of about 45 feet. Cable 53 can be connected on the other end to power converter 203 which controls power conversion up conversion and is a processing module. Cable 53 continues out of power converter 203 on the opposite side, e.g., for about 6 inches. The other end of cable 53 is connected to 19-pin ethernet cable 207 which is connected to radio 59. 19-pin ethernet cable 207 provides electrical connection, noise filtering and is a bi-directional system. The right hand side of 19-pin ethernet cable 207 is the electrical connector that interfaces with radio 59. Cable 53 preferably has neutral buoyancy, low drag, and is slightly hydrophobic, flexible, lightweight, double shielded, twisted pair, at least category 5 (e.g., a category 5e ethernet cable), and can sustain at least about 650 lbs of pull force.

Referring to FIG. 3, a functional block diagram of exemplary mobile device 49 showing the necessary components of an exemplary mobile device used in the system of the present invention. Exemplary mobile device 49 has pathway for 6-pin cable 209 to enable connectivity to external cables, input 213, output 215, processor 217, memory 219, touchscreen display system 221 for graphical user interface components 231, operating system software 223, applications 225, device drivers 227 and power supply 229. Touchscreen display system 221 responds to electromagnetic induction technology, or magnetic response generated by an exemplary specialized stylus (e.g., an S-pen stylus) utilized to interact with touchscreen display system 221 by means of digitizers incorporated in touchscreen display system 221. This touchscreen display system technology is for example referred to in U.S. Pat. No. 5,693,914, which is incorporated herein by reference. When alternative exemplary mobile devices 49 are to be used, an alternative stylus may be substituted for an exemplary specialized stylus to achieve full touchscreen functionality that may or may not require digitizers incorporated in touchscreen display system 221.

Referring to FIG. 4, a side view of buoy 55 immersed in body of water 47 with antennae 63 and deck 65 above or at the surface of the water. Deck 65 is statically fixed to upright mast 67. Upright mast 67 is positioned just below the surface of the water, supporting deck 65 and it is connected securely to body 71. Wing 69 is statically coupled horizontally on top of body 71 and radio box 73 is coupled under body 71 at the bottom of buoy 55. Pull bar 75 can be affixed to body 71 in multiple locations traversing horizontally along body 71, and tether 77 comes out of pull bar 75. Tether 77 can be connected to a diver. Buoy 55 provides a stable platform to support radio box 73 containing radio 59 (not shown) and antennae 63 that connect by cable 53 (not shown) to mobile device 49 (not shown) underwater thereby allowing various cable-enabled capabilities, e.g., navigation and communication. Deck 65 supports antennae 63 such that antennae 63 stays above water no less than 95% of the time. Deck 65 has baffle 61 which is bent up, preferably to about 20 degrees. Baffle 61 prevents water from flowing over deck 65 at low speeds and prevents sheeting of water over antennae 63 at higher speeds. Baffle 61 minimizes drag in addition to keeping splash down. About half of deck 65 can be out of the water when buoy 55 is stationary, and deck 65 can be roughly level with the water when buoy 55 is not moving. Deck 65 is maintained just above the surface of the water through the buoyancy of deck 65 and of wing 69. The buoyancy of wing 69 and deck 65 are sufficient to keep radio box 73 and other components at a stable level in the water. Deck 65 in particular acts as a deflector and buoyancy manipulator, producing repellant drag and correction. For example, when deck 65 hits the water, it pulls the system back up. The buoyancy of the system of the present invention can be positive, neutral or negative depending on the forces being exerted on buoy 55 (see FIG. 6).

Radio box 73 provides an area where radio 59 (not shown) and other items can be inserted. For example, radio box 73 additionally can have a phone ballast to make sure that radio 59 (not shown) does not move around or it could be filled with foam to reduce the sound of radio 59 (not shown), and to decrease the weight of the system and to increase buoyancy. The weight of radio box 73 with radio 59 (not shown) and other items have sufficient weight such that in combination, these provide for a self-correcting buoy system that can balance the system at varying depths and further prevent the system from not tipping over onto its side. Exemplary cables run from radio 59 (not shown) up upright mast 67 to antennae 63 supported by deck 65. Antennae 63 are kept just above the surface of the water, preferably over 95% of the time that buoy 55 is immersed in body of water 47, so that they can continue to communicate signals to radio 59 (not shown). Antennae 63 link up to a transceiver that simultaneously receives and transmits data. Antennae 63 further preferably enable connection to exemplary mobile ad hoc networks. Body 71 of buoy 55 allows for the placement of radio box 73 at a depth below the center of buoyancy of buoy 55 and upright mast 67 keeps deck 65 at a height above the center of buoyancy of buoy 55. Body 71 also allows for the connection of pull bar 75. Pull bar 75 can freely pivot, via en exemplary hinge feature, preferably enabled by exemplary push lock retaining pin 101 fitting through exemplary hole 109. The exemplary hinge feature enables the angle of pull bar 75 to change depending on the depth of the diver in relation to the surface of the water and can be adjustable (see FIG. 9) to change the lift-drag dynamics and to accentuate wing 69 up to max speed.

In one exemplary embodiment of the present invention, buoy 55 is designed to be preferably pulled at speeds of up to 4 knots with a pull angle of 0 to 45 degrees.

In another exemplary embodiment of the present invention, buoy 55 has static stability such that the center of buoyancy is directly above the center of gravity, keeping buoy 55 upright when it is not moving or is moving at speeds less than 1 knot.

In yet another exemplary embodiment of the present invention, antennae 63, though preferably for radio 59 (not shown) connectivity to ethernet, GPS, and communications, can alternatively be configured to serve other functionality requirements for a variety of exemplary mobile devices 49 (not shown) utilized by an operator.

Referring to FIG. 5, a front view of buoy 55 with constituent components antennas 63, just above deck 65 both held up by upright mast 67 and wing 69 which functions as stabilizing buoy 55. Below wing 69 is body 71 and pull bar 75 affixed to body 71 with radio box 73, situated right below body 71. Tether 77 runs through pull bar 75. It is intended that pulling tether 77 to the left or to the right will change the direction that buoy 55 is being pulled. Pull bar 75 is rigid to facilitate this exemplary directionality of buoy 55. Deck 65 can have positive buoyancy to balance out buoyancy of the other components of buoy 55.

Referring to FIG. 6, a front view of buoy 55 showing exemplary lift forces 79 when tether 77 exerts a tension force 81 on buoy 55. In one exemplary embodiment of the present invention, wing 69 stays completely underwater to provide exemplary lift forces 79 when buoy 55 is moving. Generally, deck 65 can have neutral buoyancy at one water line, which ensures that the water line stays at deck 65. Arrangement of wing 69 and deck 65 can also provide negative feedback on exemplary lift forces 79 of wing 69, and this keeps wing 69 at a constant depth. When deck 65 begins to submerge, positive buoyancy is exhibited, e.g., exemplary lift forces 79 counter tension force 81 exerted by tether 77. When deck 65 is too low in the water, buoyancy and hydrodynamic lift cause deck 65 to rise, and levels the angle of wing 69 to the horizontal, lifting buoy 55 higher. Similarly, when deck 65 gets too high out of the water, negative buoyancy is exhibited, e.g., gravity causes buoy 55 to tilt forward, and this causes the angle of wing 69 to drop toward the vertical. Pull bar 75 pivots below wing 69. Pull bar 75 has a variable pitch angle that modifies wing 69. Via pull bar 75, a pull force (not shown) passes through an exemplary center of lift and through the center of buoyancy of wing 69. Thus, differences in pull angle do not greatly affect the stability of buoy 55. The positive, neutral, and negative buoyancy forces of the system maintains the system at a stable depth when at rest, and when under dynamic load, e.g., when it is being pulled and dragged forward. Buoyancy of the system is a function of lift and transit. The buoyancy of the present invention works via wing 69 which provides lift and drag, based on the angle of the pull established, e.g., lift is provided when there is a forward force and drag is provided when there is a backward force. Critical to the buoyancy of buoy 55 is that the weight is minimized, the structural strength is maximized and the system is balanced. These elements in combination with the components described herein right the structure of buoy 55.

Referring to FIG. 7, a perspective view of wing 69. Wing 69 provides lift and drag, not buoyancy. The shape of wing 69 allows for it to correct for lift as buoy 55 is pulled through the water. Wing 69 is a hydrodynamic shape created from carbon fiberglass covered honeycomb composite, and the component is large for neutral buoyancy, and lightweight. The hydrodynamic shape of wing 69 provides lift (See FIG. 4) to keep buoy 55 level in the water and to prevent it from going underwater as buoy 55 begins to move.

Referring to FIG. 8, a bottom view of wing 69 of FIG. 5, showing wing 69 with exemplary wing bracket 83 affixed to wing 69 for connection to body 71 (not shown). Exemplary wing bracket 83 has two ledges with slots 107 opposite each other where body 71 (not shown) slides into and where preferably screws 85 can be used to affix wing 69 to body 71 (not shown).

FIGS. 9-11 are views from the bottom of wing 69. Referring to FIG. 9, the preferred installation location to preferably rigidly coupled upright mast 67, wing 69, and body 71. Installed upright mast 67, wing 69, and body 71 are oriented at mutually perpendicular orientations relative to the other. Body 71 is coupled to wing 69 on a top edge of body 71. Body 71 is independently coupled to upright mast 67 on a front edge of body 71. Wing 69 and body 71 can be coupled by body 71 slipping into wing bracket 83 with slots 107 in wing bracket 83 aligning with exemplary holes 109 in body 71 whereby wing 69 and body 71 can be coupled, preferably using exemplary screws and locknuts 85 on the bottom edge of body 71. Preferably, to install upright mast 67 onto body 71, the bottom half of upright mast 67 is split. The split bottom end of upright mast 67 slips over the front edge of body 71. Upright mast 67 can be aligned with alignment holes 103 in body 71. Upright mast 67 and body 71 are coupled preferably using a second set of screws and locknuts 105, through alignment holes 103. Exemplary RF cables are also shown, GPS cable 91, and communications cable 93.

FIG. 9 also shows the preferred pull bar 75 installation location, below wing 69. Pull bar 75 can be preferably coupled to body 71 via exemplary push lock retaining pin 101 fitting through one of a plurality of exemplary holes 109 in body 71, and can be fitted through slots 107 aligning with one of a plurality of exemplary holes 109 in body 71. Pull bar 75 can be connected to body 71 via a plurality of possible hinge points near wing 69, shown as a plurality of exemplary holes 109. Adjustment of the hinge point location of pull bar 75 requires horizontally traversing to another of plurality of exemplary holes 109 along body 71. Similarly, the installation location of wing 69 can also be adjusted via plurality of exemplary holes 109 being horizontally traversed along body 71. Preferably, exemplary push lock retaining pin 101 couples wing 69 to body 71, concurrent to affixing pull bar 75 to wing 69 and to body 71. Adjusting the location of pull bar 75 and/or wing 69 via modification of the hinge point connection chosen, e.g., selecting a different one of plurality of exemplary holes 109, can change the lift and drag for different diver lengths and depths. This ability to adjust the location of pull bar 75 and/or wing 69 is critical to performance of buoy 55 because it allows the system to be adjusted so that it is in balance at varying depths. Exemplary push lock retaining pin 101 allows pull bar 75 to freely pivot around on a vertical axis. The angle of pull bar 75 changes depending on the depth of the diver in relation to the surface of the water and the resulting forces being exerted on pull bar 75.

Referring to FIG. 10a , the preferred cable routing prior to radio 59 (not shown) installation, proper cable routing is required for buoy 55 to fly correctly through the water. Buoy 55 is propped upside down and held by wing 69 to show the preferred cable routing. Referring to FIG. 10b , the cable routing coming from deck 65 and running down upright mast 67 where GPS cable 91, and communications cable 93 from antennas 63 pass through holes 87 at the bottom of deck 65, and are affixed to upright mast 67. Referring back to FIG. 10a , GPS cable 91 runs through a second hole 89 on the bottom of body 71 thus affixing to body 71 of buoy 55.

Referring to FIG. 11, the preferred cable routing prior to radio box 73 (not shown) replacement where radio 59 allows for GPS and communications with the tablets or cell phones in the field. The present invention enables use of these implements underwater. Radio 59 is required for full underwater mobile device functionality. GPS cables 91, and communications cable 93 connect to ports 95, 97 in radio 59. External connector 57 connected to 19-pin ethernet cable 207 of cable 53 (not shown) is also connected to radio 59 and will be described more thoroughly below.

Referring to FIG. 12, the preferred cable routing through radio box 73 is shown. External connector 57 allows connection to cable 53 and runs through a front slot 99 in radio box 73. Communications cable 93 also runs through front slot 99. GPS cable 91 is affixed to the side of body 71 as described above. Cable 53 runs from radio 59 (internal to radio box 73) to underwater mobile device 49 (not shown).

Referring to FIG. 13, an alternate embodiment buoy 155 immersed in body of water 47. Alternate embodiment buoy 155 is designed for travel through body of water 47 at higher speeds than buoy 55 is capable of. In addition to the features described above for buoy 55 (not shown), e.g., deck 177, baffle 179, antennae 181, mast 183, body 171, radio box 185 with exemplary radio 187 (not shown), and tether 189, alternate embodiment buoy 155 additionally has: trailing edge pivot 157, movable rudder 161, and pull bar pivot 159. Pull bar pivot 159 allows pull bar 175 to swing from side to side as well as front to back, decreasing the ability of buoy 155 to flip. This change necessitates a change in the shape of body 171 to accommodate the increased range of motion of pull bar 175. Movable rudder 161 allows left and right motion such that pulling to the right causes movable rudder 161 to steer buoy 155 to the right. Trailing edge pivot 157 adjusts the pitch of each half of wing 169, causing buoy 155 to bank left when it is pulled left. Alternate embodiment buoy 155 provides stability for travelling at greater speeds than buoy 55 is capable of, where stability is defined as keeping antennae 181 above the surface of the water, preferably over than 95% of the time that alternative buoy 155 is in operation immersed in body of water 47. Antennae 181 are preferably for radio 187 (not shown) connectivity to ethernet, GPS, and communication, but can be reconfigured or replaced to serve alternative functionality requirements for a variety of exemplary mobile devices 49 (not shown) utilized by an operator. Antennae 181 link up to a transceiver that simultaneously receives and transmits data. Antennae 181 further preferably enable connection to exemplary mobile ad hoc networks.

Referring to FIG. 14, a front view of a fully assembled waterproof case 51 showing handle 193 on the left end of waterproof case 51 and loop 195 on the top right corner of waterproof case 51, preferably for carbiner lock-in. Waterproof case 51 encapsulates an exemplary mobile device 49 (not shown) in a waterproof encasement that is resistant to both the pressure forces exhibited at diving depths exceeding about 100 feet, and resistant to the corrosive environment of the ocean, while preserving the full functionality of exemplary mobile device 49 (not shown). In addition to sealing and protecting an exemplary mobile device 49 (not shown), waterproof case 51 permits native operation such as touch screen operation and button pushing using an exemplary stylus (not shown) when functionality at depths greater than about 10 feet is required. Up to about 10 feet waterproof case enables use of exemplary mobile device 49 (not shown) with an exemplary operator's finger. When an exemplary mobile device 49 (not shown) is inserted into waterproof case 51, the interior of waterproof case 51 can be cleaned, preferably with isopropyl alcohol. Micro USB connector 153 of FIG. 2 is plugged into exemplary mobile device 49 (not shown) and exemplary mobile device 49 (not shown) is laid down onto clear screen 191 of FIG. 19e with touchscreen facing clear screen 191. Exemplary mobile device 49 can be optimally slid towards the opposite end of the case from micro USB connector 153 to ensure easiest access once case is assembled to an exemplary home button on exemplary mobile device 49.

In one exemplary embodiment of the present invention, in addition to clear screen 191, waterproof case 51 can have a window in the back for taking pictures with an exemplary mobile device 49 (not shown).

Important to the design of waterproof case 51 was making sure that an exemplary mobile device contained within the waterproof case 51 not would not crush itself at the exemplary operational depths, e.g., exceeding about 100 feet, but also would neither corrode or dissolve in an exemplary ionic oceanic environment. To achieve this, alloy and material selection based on the electronegativity between the case and the ocean was critical. Special paints were selected and the waterproof case 51 was allodined to protect from additional corrosion. Also critical to the design of waterproof case 51 was functionality and usability as further described below.

Referring to FIG. 15, a back view of a fully assembled waterproof case 51 showing handle 193 which aids in gripping waterproof case 51 and loop 195. Also, stylus case 197 can be attached to the back of waterproof case 51, and bottom plate 199 which is coupled to the body of waterproof case 51, e.g., via screws. An exemplary stylus in stylus case 197 should be watertight, e.g., preferably exemplary specialized stylus 145 (not shown).

FIG. 16 is a back view of disassembled back plate 115 of waterproof case 51 with bottom plate 199 with holster 111 coupled to bottom plate 199, preferably via screws. Stylus case 197 fits into holster 111 where stylus case 197 preferably encases an exemplary touchscreen stylus device, e.g., preferably exemplary specialized stylus 145 (not shown). Loop 195 is shown with thread 113 tied onto it. The opposite end of thread 113 ties onto stylus case 197, securing stylus case 197 to waterproof case 51, when it is not secured within holster 111.

Stylus tube 163 has an internal hollow chamber, sized to accommodate stylus cap 165, exemplary specialized stylus 145, with spring 173, and stylus back-end cap 167. Stylus tube 163 has holes 211 which allow front end 235 of stylus case 197 to flood with an exemplary liquid to equalize the pressure on the inside of stylus case 197. Stylus tube 163 additionally has an exemplary divot 233 near front end 235 where there is a narrowing of the hollow internal chamber of stylus tube 163. Spring 173 slides onto and fits around exemplary specialized stylus 145. After spring 173 is Slid onto exemplary specialized stylus 145, the back end of exemplary specialized stylus 145 fits into stylus back-end cap 167. Stylus cap 165 fits onto the writing end of specialized stylus 145.

Referring to FIG. 17c , a partially assembled stylus case 197. The entire assembly of stylus cap 165, stylus back-end cap 167, exemplary specialized stylus 145, with spring 173 fits into stylus tube 163 from back end 237 of stylus tube 163.
